I live at NE 163 and 27th NE in Shoreline. Every year (at least since '03 when we first banded this junco), I have had juncos breeding and bringing their newly fledged young into my yard (still begging and wing quivering). Year before last, I started having two males bringing their young into my yard--and fighting over whose territory, and whose "kids" could be in my yard. This year the one banded in '03 [left leg banded] was back in the yard in January and we recaptured him the third week of February. I too have never found a nest, but know that they have to be very close by. I have a green belt (Cole Nature Park) bordering my yard, and I am at about 460 ft elevation.

I tell you this, because until Thanksgiving of 2001, I lived 28 blocks further
south at NE 135 and 22NE and I only had juncos from about early Oct until
March-April of the following year. [Elevation about 200ft]
When I moved "north" I had to learn the junco's song, because until then I had
only heard their call notes.

Oh, as an aside, Puget Sound Bird Observatory banders have been collecting
winter banding data that shows other sub-species of dark-eyed juncos migrate
here and use this area as their wintering ground; based on a significant
difference in wing length of birds banded in the winter versus the juncos
banded in the summer.

As for cosmic bird sightings, I think any bird sighting (except the dreaded
three--starlings, house sparrows and crows) is exciting--I never get tired of
watching what they do. Who knows what they will do next? Guess that's what
makes me a bird watcher...
